Method and apparatus for cleansing and disinfecting a flushing toilet comprising a toilet tank and a toilet bowl by treating the water discharged from the toilet tank each time the toilet is flushed. First and second passive dispensing apparatus for immersion in the toilet tank water are provided to carry out the cleansing and disinfecting method. The first passive dispensing apparatus contains a solid, water soluble, surfactant containing cake for exposure to a quantity of water to form an aqueous surfactant containing solution within the first dispensing apparatus. The second passive dispensing apparatus contains a solid, water soluble, disinfectant containing cake for exposure to a second quantity of water to form an aqueous, disinfectant containing solution within the second dispensing apparatus. Each dispensing apparatus isolates both the cake and the aqueous solution made therefrom from the water surrounding the dispensing apparatus intermediate flush cycles of the toilet and discharges a predetermined quantity of aqueous solution into the toilet tank when the toilet is flushed. The first dispensing apparatus is so constructed that the aqueous surfactant containing solution discharged therefrom is of substantially constant strength, while the second dispensing apparatus is so constructed that the aqueous disinfectant containing solution discharged therefrom is substantially free of undissolved solids. The isolation provided by each dispensing apparatus permits co-dispensing surfactant containing and disinfectant containing aqueous solutions which chemically react with one another upon contact to provide effective cleansing and disinfecting of the toilet. |
